Crane systems are used worldwide and across industries for transporting goods in intralogistics, in warehouse management or in various production processes. The loads here are often very high and the environment also places enormous demands on the sensor technology. In addition, the operator must always be aware of the absolute position of the crane or the control system.
This applies all the more if there are two or more cranes on one runway. For correct positioning and to avoid collisions of cranes, laser sensors are usually used, which meet common performance requirements under normal ambient conditions. However, if the level of contamination in a hall is high or if the cranes are operated outdoors, laser-based systems reach their limits.
Bang Kransysteme has put Balluff's Long Distance Positioning System through its paces: "The distance measuring system, which travels with the crane and is approx. four meters long, detects the position sensors which are mounted along the travel path according to a predefined scheme and calculates the absolute crane position from this. If knowledge of this position is indispensable even under adverse conditions, the system is ideally suited," summarises David Böttiger, Head of Automation.
